A horn’s core begins as a small growth under the skin, over the skull, known as ossicones. They’re composed of a bony core covered with a sheath of keratin. These occur in males of all species of cloven-hoofed animals. Horns are a pair of permanent, keratin structures protruding from an animal’s front part of its skull. Then, both males and females grow antlers. One interesting fact about antlers and animals is that they are present only in males. Males are without antlers for a few months in late winter until the cycle begins again during each. When the attachment is weakened the antlers fall off. Once the days begin to get shorter in winter, the pedicel loses calcium, weakening the point of connection between it and the antler. Antlers are useful in social interactions and competition for females. Males use their full-grown antlers during the mating season, sometime between August and October. Any remaining velvet is removed when the animal rubs his antlers against trees or other vegetation. During the last stages of growth, velvet begins to fall off and they’re filled with coarse, spongy, lamellar bone, and marrow spaces. Antlers grow from the supporting structures that develop in the lateral region of the frontal bones called pedicels.Īs antlers grow, they are covered with velvet, which transports nerves and blood vessels. They have been reported growing up to 200 inches (508 centimeters) depending on the species and age.
